The DevOps 2.0 Toolkit: Automating the Continuous Deployment Pipeline with Containerized Microservices

By Viktor Farcic

This ebook is ready diversified thoughts that support us architect software program in a greater and extra effective approach with microservices packed as immutable boxes, verified and deployed constantly to servers which are instantly provisioned with configuration administration instruments. it is approximately speedy, trustworthy and non-stop deployments with zero-downtime and talent to roll-back. it truly is approximately scaling to any variety of servers, layout of self-healing platforms able to recovery from either and software program disasters and approximately centralized logging and tracking of the cluster.In different phrases, this e-book envelops the total microservices improvement and deployment lifecycle utilizing a number of the most modern and maximum practices and instruments. we are going to use Docker, Kubernetes, Ansible, Ubuntu, Docker Swarm and Docker Compose, Consul, etcd, Registrator, confd, etc. we are going to plow through many practices or even extra instruments. eventually, whereas there'll be loads of conception, this can be a hands-on ebook. you will not manage to whole it through interpreting it in a metro on how to paintings. you will have to learn this booklet whereas in entrance of the pc and get your palms soiled.

Attempt and the Dockerfile that outline trying out and repair boxes, Docker Compose configurations that outline how should still packing containers be run and, ultimately, the proxy configuration and template. All these documents are separated from the method we’re developing, and folks in command of the venture have the whole freedom to tailor them to their wishes. That showcases a crucial point I’m attempting to advertise. it's important not just to have definitely the right procedure in position but additionally to have the scripts, configurations and the code accurately situated.

Conf the results of the second one command is as follows. 1 2 three The handle is 10. a hundred. 194. 201:4321 The handle is 10. a hundred. 194. 201:1111 The Consul Template command we carried out came across either providers and generated the output within the layout we special. We targeted that it's going to run just once. the choice is to run it in daemon mode. In this kind of case, it can display screen the registry for adjustments and observe them to detailed configuration documents. we'll cross into info of the way Consul Template works afterward once we commence utilizing it in our deployment pipeline.
